METAL WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented March 24:, 1908.

Application filed April 24, 1905. Serial No. 257,151.

To all whom it may concern:

Be it known that I, GEORGE H. FoRsYTn, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Metal /Vindow Constructions, of which the following is a specification.

My invention relates to metal window constructions; and has reference more particularly to a construction of window frame or casing and sash designed to afford an elastic or yielding engagement between the sash and its frame or casing guides, so as to produce a practically dust-proof and anti-rattling fit between said parts; a further object-of the invention being to allow adjustability in the plane of the sash between the latter and the casing or casing guides.

According to my present invention, the yielding or elastic fit between the sash and the casing guides is secured wholly or partially by making the guide itself yielding or elastic, either in a direction transversely of the sash or. parallel with the sasluior both.

My invention also relates to a novel means for securing the glass in the sash, according to which the sash is supported on one side by a glass-holding strip which may constitute an integral extension of the sash frame, and on the other side by a separate strip, suitably united to the latter.

My invention also contemplates an. im proved manner and means of uniting the stiles and bars of the sash at the corners, such uniting means permitting transverse yielding or elasticity of the stiles, when desired.

My invention, in several approved forms, is illustrated in the accompanying drawing, wherein-- Figure 1 is a front elevational view, broken away intermediate its sides, of a metal sash constructed in accordance with my invention; the same showing on one side a. square joint between the stile and bars, and on the other side a mit-ered joint between said. parts; Fig. .2 is a top edge view of Fig. l

Fig. 3 is a left hand edge view of Fig. 1 Fig. 4 is a right hand edge view of Fig l; partly broken out Figs. 5, 6 and 7 illustrate various forms andconstructions of glass-holding means; and Figs. 8 to 12. inclusive, are cross-sectional detail views, illustrating various f rms :of transversely elastic casing guide" Fig. 9 showing the same cooperating with a non-elastic sash member, and the remaining figures showing guides cooperating with transversely elastic sash members.

lteferring to the drawing, 15 and 15 may designate, as entireties, the stiles, and 16 the bars of a hollow metal sash frame, containing the glass 17. The bars 16 are preferably closed at their upper and lower edges, respectively, excepting at their ends to approximately the extent of the width of the underlying stiles 15, where they are left open to afford transverse elasticity to the stiles from to to bottom of the sash frame. The stile 15 is preferably open throughout the entire extent of its outer edge, as shown in Fig. 3; while the stile 15 has a closed outer edge, shown in Fig. 4. it is to be understood that in practice the sash may have both stiles formed with open or with closed outer edges, as desired the two constructions being shown in connection with a single sash merely for the purpose of condensing the illustration.

Referring first to the means which I have devised for uniting the sash frm'ncmembers at the corners, l8 designates elbow-shaped cleats which are preferably formed of sheet metal suitably bent to provide parallel side walls .18 and an inner rectangular transverse wall 18*. Said connecting members are socurely riveted by their side walls to the inner surfaces of the parallel face members of the stile 1.5 and bars 16, the rivet-lug bcing ca 3ablc of performance by the aid of a suite )lc mandrel inserted into the hollow connecting member through the open edge or end of the stile. Similar connecting members 18 may be employed to unite the mitercd joints be tween the stile l5 and the bars 16; but in this case, it being impossible to enter a mandrcl on account of the closed cdgc formation of the stile 15, the fastening may be effected by rivets 19 extending entirely through the sash frame. with spacing sleeves 20, sur

rounding said rivets between the inner walls of the connecting member l8, all as shown .in Fig. 4 and at the right of Fig/l.

Referring next to the menus for holding the glass in the sash frame, which is"illus traicd more particularly in Figs. 5, 6 and 7, and referring first to Fig. 5, it will be observed that in said figure the sheet metal of the stile 1:3 on one side of the glass is carried inwardly of the edge of the glass and then bent back, forming an integral elastic glassholding lip 21. The same inner edgcof the eted thereto, said channel strip contaimng a stileis further provided with a dovetailed re entrant portion 22 formed by suitably bendin .the metal, which portion is preierably ed by a wooden stri 23 against which the edge of the glass seats, t eglass being retained in place by a wooden fastening stri 24' secured to t screws 25 and cooperating with the integral lip 21 in securely holding the lassunder sprin or tension engagement in t e sash.

In 6 the metal of the stile is projected inwardly and then cutofi, forming a single rounded ii 26 en a ing the glass, the face' members 0 the st' e eing united at their inner edges by a channel strip'27 suitably rivwooden strip 28 secured thereto as by, means of pins or brads 29' andscrews 29, forming an abutment for theed e of the glass 17. Against the o posite si e of the glass 17 abuts, preferalily under elastic engagement,

the metal strip 24, whose offset lower portion 24 enters into the channel strip 27, where p it is held in position by the screws 29.

' In Fig. 7 the inner margins of the side walls -of the stile 15 are bent inwardly, forming the r'eentrant pocket 32 within which is located the inversely disposed channel filling strip ii 30, between whose side Walls 30? and the in nor Walls 32 of the pocket 32 are inserted the lower offset portions 31 of the metal strips 31, which preferably engage the glass under springtension and are held in osition by the screws 33, having nuts 33 within the jilling strip 30, whose transverse wall forms a seat for the glass 17. It is evident that the above described means for holding the glass may be emplo ed in connection with the bars as well as Wit the stiles.

Figs. 8 to 12, inclusive, show various forms of yiel'dable or elastic casing guides. 'In Fig. 8, 34 may represent in cross-section a portion of a, wooden casing member, fastened to which'by the screws 35 is the elastic guide. or rib 35, whose outwardly flaring wings 36 vides for transverse elastic engagement between the-casing and the sash, as well as for plane of the sash.

sidewise adjustment therebetween in the In Fig. 10, 38 may designate a portion of a hollow metal casin 'mem er, the inner wall of which is suitably ent to forma guide s ace e5 39, one eds-waneswiitaaconaauad y ae strip 23 as by suitable rads ordetachable strip 35 with the elastic sashco'ntacting tongue 37, said strip being secured in place as by a screw bolt 40 and nut 41. Cooperating with the guide groove thus formed I have shown a hollow stile 15, that is transversely elastic, and has the outer margin of one of its face members inwardlybent or inclined, asshown at 42, on substantially the same angle as that of the oblique guide withdrawn from engagement with the casing uide the side walls of said stile preferablyare outwardly, thereby increasing the tension between the latter and the casing guide.

In the construction of Fig. 11, 43 may represent the inner face of the hollow metal casin member, to which is secured, as bymeans ofolts 44 and 45, the former having a spacin sleeve 46, a bent metal guide47. One side wall of said guide is formed by an oblique elastic tongue 37, while the other is constituted by an S-shaped bend 48, the inner end of which 48 projects inwardly sufiiciently to members 15 lying within the stile 15. In this'construction the'tongue 37 affords a atter, while the elastic projection 48 enga ing the edge of the sash member 15 afforr s an elastic pressure upon the latter in the direction ofits plane. It must be evident that the edges of the stile 15 may be sufficiently casing guide 47 as well as' the sash member I 15. In the latter case I prefer to have both the sash member 1 5 and the stile 1 5 fiareout: Wardly; whereas if only the former engage the "casing guide the stile is formed either with its side walls parallel to each other or slightly inwardly inclined along their outer margins. v

In the constr ction shown in El 12, the form of the sash guide shown in %ig. 11 is varied so as to substitute for the outwardly pressing member 48 a companion 37 to the pressure upon both faces of the sas member 15 when entered therebetween.

It will be" observed that the inclined lip construction, when constituting one side 'bined lateral and Widthwise pressure u on sash in 'both wi to the casing.

,While I have shown-.thesas'h member engaging the casing guide with one of its inner margins inwardly inclined it must be evidentinwardl outwar ly', without departing from the principle of my invention.

It being evident that the invention as tongue 37 and engaging, the latter.
